Regularized Bayesian calibration and scoring of the WD-FAB IRT model improves predictive performance over marginal maximum likelihood [PDF]
PLoS ONE 17(4): e0266350 (2022), 2020 Item response theory (IRT) is the statistical paradigm underlying a dominant family of generative probabilistic models for test responses, used to quantify traits in individuals relative to target populations. The graded response model (GRM) is a particular IRT model that is used for ordered polytomous test responses.

Method of successive dichotomizations: An improved method for estimating measures of latent variables from rating scale data. [PDF]
PLoS ONE, 2018 The most commonly used models for estimating measures of latent variables from polytomous rating scale data are the Andrich rating scale model and the Samejima graded response model. The Andrich model has the undesirable property of estimating disordered

Frontiers in Rehabilitation Sciences, 2023 The application of the Rasch measurement model in rehabilitation is now well established. Both its dichotomous and polytomous forms provide for transforming ordinal scales into interval-level measures, consistent with the requirements of fundamental ...

Multilevel IRT Modeling in Practice with the Package mlirt [PDF]
, 2007 Variance component models are generally accepted for the analysis of hierarchical structured data. A shortcoming is that outcome variables are still treated as measured without an error.

Judging similarity versus judging difference
Frontiers in Education, 2023 A key feature of the polytomous Rasch model is that it entails a single classification process into one of a set of ordered response categories. The first aim of this article is to make explicit two processes in rubric designs that bring about such ...
